INSTALLING CLUTCH/IDLER ASSEMBLY

This section covers the installation of the Clutch/Idler

assembly to tractors with attachment clutches that are

either rod operated (p. 9), cable operated (p. 10) or

electric (p. 12). Use the appropriate instructions for

your tractor.

MANUAL ROD OPERATED ATTACHMENT CLUTCH

• Move the attachment clutch lever on the dash

panel to the disengaged (down) position.

• Screw the trunnion onto the end of the snow

thrower engagement rod as shown in figure 11.

• Locate the clutch arm (where the mower clutch rod

was connected) underneath the right hand side the

tractor, just to the inside of the suspension arm. If

there is an extension attached to the clutch lever,

the extension, bolt and nut must be removed and

stored with the mower deck.

IMPORTANT: Re-attach the extension to the

clutch lever before reinstalling the mower deck.

• Position the engagement rod to the inside of the

clutch arm and insert the drilled end of the rod

through the arm. Secure with a 5/64" hairpin cotter.

See figure 11.

• Be sure to lift up the front end of the engagement

rod (as shown in figure 12) when performing the

next operation. You can temporarily support the rod

using a rubber band tied to the engine pulley

keeper.

• Attach the clutch/idler assembly to the tractor frame

as follows. Hook the assembly's notched arms onto

the two shoulder bolts you assembled to the inside

of the tractor frame. Lift the front of the assembly

and attach it to the R.H. and L.H. hanger brackets

using two pivot lock pins and 1/8" hairpin cotters.

See figure 12.

• Make sure the attachment clutch lever on the dash

panel is in the disengaged (down) position.

• Pivot the upper idler arm so that it rests against the

stop bolt and is pointing toward the front as shown

in figure 13. Screw the trunnion along the threads

of the engagement rod until it is aligned at the front

end of the idler arm slot. Attach the trunnion to the

slot using the 3/8" flat washer and a 5/64" hairpin

cotter. See figure 13.

• Remove the engine pulley keeper from the side of

the tractor frame by removing the washer and nut

that secure the keeper. Attach the new pulley

keeper supplied with the snow thrower, reusing the

original bolt, washer and nut. See figure 13.

NOTE: Some tractors may already be equipped

with an identical pulley keeper.
